MY KINGDOM FOR A 'PLANE: Mark Grimsley speculates that one accident was the difference between the survival and the fall of France, and maybe the scale of the Holocaust. Its a provocative piece, but I'm skeptical.

Case Yellow had many things in its favor and everyone should read the book. The German command chose Case Yellow because wargames showed it had a much better outcome and because the German Officer-Intellectuals pushed it very hard.

The French fought hard in many locations but were undone by their Operational Commanders who were too slow to think and much slower to act.
